Abstract
The parameters of the -- model in the
relativistic mean-field theory with nonlinear -meson
self-interaction are determined by nuclear-matter properties, which
are taken as those extracted by fits to data based on nonrelativistic
nuclear models. The values of the relevant parameters are
,
,
,
, , and the -meson mass
MeV, while the value of the calculated nuclear-
surface thickness is fm. The field system is shown to be
stable, since the -meson self-interaction energy is a lower
bound in this whole parameter region with positive c. On the
other hand, the effective nucleon mass M* is larger than 0.73M,
if the symmetry incompressibility Ks is assumed to be negative
and the nuclear-matter incompressibility K0 is kept less than
300 MeV.
